                      CALPINE CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 March 31, 2000
                                   (unaudited)


1.       Organization and Operation of the Company

Calpine  Corporation  ("Calpine"),  a  Delaware  corporation,  and  subsidiaries
(collectively,  the "Company") is engaged in the  development and acquisition of
power projects and generation of electricity in the United States and Canada.

2.       Summary of Significant Accounting Policies

Basis of Interim Presentation -- The accompanying interim consolidated financial
statements  of the Company have been  prepared by the Company,  without audit by
independent  public  accountants,  pursuant to the rules and  regulations of the
Securities  and  Exchange  Commission.   In  the  opinion  of  management,   the
consolidated  financial statements include the adjustments  necessary to present
fairly the information required to be set forth therein. Certain information and
note  disclosures   normally  included  in  financial   statements  prepared  in
accordance with generally accepted accounting  principles have been condensed or
omitted  from  these  statements  pursuant  to such rules and  regulations  and,
accordingly,  should  be read  in  conjunction  with  the  audited  consolidated
financial  statements of the Company  included in the Company's annual report on
Form 10-K for the year ended December 31, 1999. The results for interim  periods
are not necessarily indicative of the results for the entire year.

Use of Estimates in  Preparation of Financial  Statements -- The  preparation of
financial statements in conformity with generally accepted accounting principles
requires  management to make estimates and assumptions  that affect the reported
amounts of assets and  liabilities,  and  disclosure  of  contingent  assets and
liabilities at the date of the financial  statements and the reported amounts of
revenues and expenses during the reporting  period.  Actual results could differ
from  those  estimates.  The most  significant  estimates  with  regard to these
financial  statements relate to future development costs and useful lives of the
generation facilities (see Property, Plant and Equipment, net).

Capitalized  interest -- The Company capitalizes interest on capital invested in
projects during the  construction  period.  For the three months ended March 31,
2000 and 1999,  the Company  recorded net interest  expense of $17.9 million and
$21.0 million,  respectively,  after capitalizing $25.1 million and $2.3 million
of interest on general  corporate funds used for  construction in 2000 and 1999,
respectively, and after $4.8 million and $1.5 million of interest capitalized on
funds   borrowed   for  specific   construction   projects  in  2000  and  1999,
respectively.  Upon the start-up of plant  operations,  capitalized  interest is
transferred to property, plant and equipment and is amortized over the estimated
useful life of the plant.  The  increase  in the amount of interest  capitalized
reflects the  significant  increase in the  Company's  power plant  construction
program.

New  Accounting  Pronouncements  --  In  June  1999,  the  Financial  Accounting
Standards Board ("FASB") issued Statement of Financial  Accounting  Standards ("
SFAS")  No.   137,   "Accounting   for   Derivative   Instruments   and  Hedging
Activities--Deferral  of the  Effective  Date  of  FASB  Statement  No.  133--an
Amendment of FASB Statement No. 133". The Statement amends SFAS No. 133 to defer
its effective date to all fiscal  quarters of all fiscal years  beginning  after
June 15, 2000.  The Company has not yet  completed its analysis of the impact of
adopting SFAS No. 133 on the financial  statements  and has not  determined  the
timing of or method of the  adoption of SFAS No.  133.  However,  the  Statement
could increase the volatility of the Company's earnings.

Reclassifications  --  Prior  period  amounts  in  the  consolidated   financial
statements  have  been  reclassified  where  necessary  to  conform  to the 2000
presentation.

(1)  The Company  acquired an additional  50% interest in the Aidlin Power Plant
     on August 31, 1999.  Accordingly,  the Company thereafter  consolidated the
     operations of the Aidlin Power Plant.

(2)  On December  17,  1999,  the Company  acquired  80% of the common  stock of
     Cogeneration  Corporation of America  ("CGCA")which  has a 50%  partnership
     interest in the Grays Ferry Cogeneration Partnership.

5.       Trust Preferred Securities

On January 26,  2000,  Calpine  through  its  wholly-owned  subsidiary,  Calpine
Capital  Trust II, a  statutory  business  trust  created  under  Delaware  law,


                                       7


completed a private offering of 6,000,000  Remarketable  Term Income  Deferrable
Equity Securities  ("trust preferred  securities")  ("HIGH TIDES") at a value of
$50.00 per share. The gross proceeds from the offering were $300.0 million.

On February 10,  2000,  Calpine,  through its  subsidiary,  privately  placed an
additional  1,200,000 trust preferred  securities at a value of $50.00 per share
pursuant to the exercise of the underwriters'  over-allotment  option generating
gross proceeds of $60.0 million.

The net proceeds from the offerings were used by Calpine's  subsidiary to invest
in convertible subordinated debentures of Calpine, which represent substantially
all of the subsidiary's  assets.  Calpine  effectively has guaranteed all of the
subsidiary's  obligations  under  the  trust  preferred  securities.  The  trust
preferred  securities  are reflected on the balance sheet as  "Company-obligated
mandatorily  redeemable convertible preferred securities of a subsidiary trust",
while   distributions   are  reflected  in  the   statements  of  operations  as
"Distributions  on trust preferred  securities".  Financing costs related to the
issuance of the trust  preferred  securities  are amortized  over 30 years.  The
trust preferred  securities accrue distributions at a rate of 5 1/2 % per annum,
have a liquidation  value of $50.00 per share,  are  convertible  into shares of
Calpine's  common  stock  at the  holders  option  on or  prior  to  the  tender
notification  date,  at a rate of 0.4881  shares of common  stock for each trust
preferred security, and may be redeemed at any time on or after February 5, 2003
at a redemption price equal to 101.375% of the principal amount plus any accrued
and unpaid  distributions  declining to 100% of the principal amount on or after
February  5, 2004.  Additionally,  Calpine  has the right to defer the  interest
payments on the debentures for up to twenty  consecutive  quarters,  which would
also  cause a  deferral  of  distributions  on the trust  preferred  securities.
Currently,  the Company has no intention of deferring  interest  payments on the
debentures.

6.       Acquisitions

On January 14, 2000, Calpine acquired a 50% interest in the Aries Power Plant, a
600 megawatt natural gas-fired plant currently under  construction near Pleasant
Hill,  Missouri,  from a subsidiary of Aquila Energy  Corporation.  Construction
started in October  1999.  Commercial  operation  of the first 330  megawatts is
scheduled  to begin June 2001 with the balance of the plant  starting in January
2002.  The  majority of the  facility's  output will be sold to Missouri  Public
Service  through  May 2005.  Thereafter,  power will be sold into the  Southwest
Power Pool.

On February 4, 2000, Calpine acquired 100% of the stock of Western Gas Resources
California from Western Gas Resources, Inc. for $14.9 million.  Western's assets
include the 130-mile  Steelhead natural gas pipeline and the remaining  interest
in the  Sacramento  River Gas System  natural  gas  pipeline,  now 100% owned by
Calpine.

On March 30,  2000,  Calpine  purchased  a 78.5%  interest  in the  500-megawatt
Hidalgo Energy Center, which is under construction in Edinburg, Texas, from Duke
Energy North America for $235 million.  The purchase  includes a cash payment of
$134 million and the assumption of a $101 million capital lease obligation.  The
Hidalgo Energy Center will sell power  utilizing the Company's  system  approach
into the Electric  Reliability  Council of Texas' ("ERCOT") wholesale market and
potentially into northern Mexico. Construction of the facility began in February
1999, and commercial operation is expected in June 2000.

7.       Credit Facilities

Calpine  maintains  a credit  facility  of $100.0  million,  which is  available
through a consortium of commercial lending  institutions led by The Bank of Nova
Scotia as agent.  A maximum  of $50.0  million  of the  credit  facility  may be
allocated to letters of credit. At March 31, 2000, Calpine had no borrowings and
$39.7  million  of  letters of credit  outstanding  under the  credit  facility.
Borrowings  bear  interest  at The  Bank  of Nova  Scotia's  base  rate  plus an
applicable margin or at LIBOR plus an applicable margin. Interest is paid on the
last day of each interest period for such loans.  The credit facility  specifies
that Calpine maintain certain covenants, with which Calpine was in compliance as
of March 31, 2000.  Commitment  fees related to this credit facility are charged
based on 0.375% of committed unused funds.

On November 4, 1999,  Calpine  entered into a credit  agreement for $1.0 billion


                                       8

through its wholly-owned subsidiary,  Calpine Construction Finance Company L.P.,
with a consortium of banks with the lead arranger  being The Bank of Nova Scotia
and the lead arranger  syndication  agent being Credit Suisse First Boston.  The
non-recourse  credit  facility  will be  utilized  to  finance a portion  of the
construction  of  Calpine's  diversified  portfolio  of  gas-fired  power plants
currently  under  development.  Calpine  currently  intends  to  refinance  this
construction  facility in the long-term  capital  markets prior to its four-year
maturity.  As of March 31, 2000, Calpine had $64.3 million outstanding under the
facility.  Borrowings under this facility bear interest, at Calpine's option, at
the prime  commercial  lending rate, the Federal Funds Rate plus 0.50% or LIBOR.
The credit facility  specifies that Calpine  maintain  certain  covenants,  with
which Calpine was in compliance as of March 31, 2000.  Costs associated with the
credit  agreement  have been deferred and will be amortized over the life of the
assets financed.

Additionally,  Calpine maintains other credit facilities  through certain of
its subsidiaries.


8.       Earnings per Share

Basic  earnings per share were computed by dividing net earnings by the weighted
average number of common shares  outstanding for the period. The dilutive effect
of the potential  exercise of outstanding  options to purchase  shares of common
stock is calculated using the treasury stock method. The reconciliation of basic
earnings per share to diluted earnings per share is shown in the following table
(dollars in thousands  except share data).  All share data has been  adjusted to
reflect the two-for-one stock split effective October 7, 1999.

ITEM 2.         MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                AND RESULTS OF OPERATIONS

Overview

Calpine is engaged in the development,  acquisition, ownership, and operation of
power generation facilities and the sale of electricity and steam principally in
the United States.  Today, we have interests in 44 operating power plants having
a net capacity of 3,355 megawatts,  15 power plants under construction  having a
net capacity of 6,568  megawatts,  and 13 projects under  development with a net
capacity of 7,268 megawatts.

On January 11,  2000,  we announced  our plans to expand our  presence  into the
Florida  wholesale  power  market.  Our plans are to invest  approximately  $750
million in power generation  facilities and manage these development  activities
in the  Southeast  from a new  office in Tampa,  Florida.  We will  develop  two
natural gas-fired energy centers,  the 1,080-megawatt  Blue Heron Energy Center,
to be located outside of Vero Beach, and the 540-megawatt  Osprey Energy Center,
to be located in the City of Auburndale  adjacent to an existing  power facility
in  which we have an  interest.  Construction  for the  proposed  facilities  is
planned for 2001 or 2002, with both projects  expected to commence  operation in
2003 or 2004.

On January 14, 2000, we acquired a 50% interest in the Aries Power Plant,  a 600
megawatt  natural  gas-fired plant currently  under  construction  near Pleasant
Hill,  Missouri,  from a subsidiary of Aquila Energy  Corporation.  Construction
started in October  1999.  Commercial  operation  of the first 330  megawatts is
scheduled  to begin June 2001 with the balance of the plant  starting in January
2002.  The  majority of the  facility's  output will be sold to Missouri  Public
Service  through  May 2005.  Thereafter,  power will be sold into the  Southwest
Power Pool.

On January 18, 2000,  we entered  into an  agreement  to provide the  Sacramento
Municipal  Utility District ("SMUD") with a five year supply of electricity from
our 545-megawatt  Sutter Power Plant. The plant is currently under  construction
near Yuba City,  California.  We will provide 150  megawatts of  electricity  to

Results of Operations

Three Months Ended March 31, 2000  Compared to Three Months Ended March 31, 1999

Revenue -- Total revenue  increased  56% to $235.4  million for the three months
ended March 31, 2000 compared to $150.6 million in 1999.

         Electricity and steam sales revenue  increased 51% to $193.9 million in
         2000 compared to $128.0  million in 1999. The increase is primarily due
         to the  acquisition  of 14  geothermal  facilities  from PG&E on May 7,
         1999,  which  contributed  an additional  $47.9 million during 2000. An
         additional $23.5 million was contributed by the Newark, Parlin, Morris,
         and Pryor facilities which were acquired on December 17, 1999. The King
         City  facility  contributed  $6.0 million more than for the same period
         last  year  due to  less  curtailment.  The  Clear  Lake  and  Pasadena
         facilities  reported  an  additional  $4.5  million  and $4.3  million,
         respectively,  due to favorable pricing. These increases were partially
         offset by a $20.5 million decrease in contractual  capacity payments at
         Texas City.

         Service contract revenue increased to $23.1 million in 2000 compared to
         $11.5 million in 1999. The 101% increase was primarily  attributable to
         increased energy and gas marketing and trading activity associated with
         power  and gas  obtained  from  third  parties,  which  contributed  an
         additional $11.7 million in revenue in 2000.

         Income from unconsolidated  investments in power projects decreased 10%
         to $9.8 million in 2000  compared to $10.8  million  during  1999.  The
         variance is primarily due to a $1.2 million  decrease in  distributions
         from the  Company's  investment  in the Sumas  Power  Plant,  partially
         offset by income  recorded by the Company's  investment in Grays Ferry,
         which was acquired on December 17, 1999.

         Interest  income on loans to power projects  decreased from $303,000 to
         none in 2000. On October 1, 1999, the Company completed its acquisition
         of Sheridan Energy, Inc., until which time interest income was recorded
         on  convertible  preferred  stock held by the Company.  From October 1,
         1999, the results of operations have been consolidated.

         Other  revenue  increased to $8.6  million in 2000  compared to none in
         1999. Other revenue is comprised primarily of oil and natural gas sales
         to third parties.  The increase is  attributable  to the acquisition of
         Sheridan Energy, Inc., on October 1, 1999.

Cost of  revenue  -- Cost of  revenue  increased  53% to $176.7  million in 2000
compared to $115.2  million in 1999.  The $61.5  million  increase was primarily
attributable to $51.2 million in incremental effects of acquisitions consummated
after March 31, 1999 on plant  operating  expenses,  fuel expense,  depreciation
expense,  operating lease expense,  and production  royalties  expense.  A $10.3
million  increase in service  contract  expense was  attributable  to  increased
energy and gas  marketing  and trading  activity  associated  with power and gas
obtained from third parties.

General  and  administrative  expenses -- General  and  administrative  expenses
decreased  5% to $8.6  million  for the three  months in 2000  compared  to $9.1
million in 1999.  The decrease  was  primarily  attributable  to the effect of a
reserve for leasehold improvements made in 1999.

Interest  expense -- Interest  expense  decreased  15% to $17.9  million for the
three  months in 2000  from  $21.0  million  for the same  period  in 1999.  The
decrease was primarily  attributable to interest  capitalized on corporate funds
invested  in   construction   projects  of  $25.1   million  and  $2.3  million,
respectively,  which was offset by  increased  interest  expense  on  additional
borrowings during 1999.

Provision  for income taxes -- The effective  income tax rate was  approximately
39% for the three  months  ended  March 31, 2000 and 1999.  The  increase in the
nominal provision was due to higher taxable income in 2000.

Outlook

Our strategy is to continue our rapid growth by  capitalizing on the significant
opportunities in the power market,  primarily through our active development and
acquisition  programs.  In pursuing our proven growth  strategy,  we utilize our
extensive  management  and technical  expertise to implement a fully  integrated
approach to the  acquisition,  development  and  operation  of power  generation
facilities.   This  approach   uses  our   expertise  in  design,   engineering,
procurement,  finance,  construction management,  fuel and resource acquisition,
operations and power  marketing,  which we believe provide us with a competitive
advantage. The key elements of our strategy are as follows:

    o   Development and expansion of power plants.  We are actively pursuing the
        development  of new and the  expansion  of  existing  highly  efficient,
        low-cost,  gas-fired  power  plants  that  replace  old and  inefficient
        generating  facilities  and  meet the  demand  for new  generation.  Our
        strategy is to develop  power plants in strategic  geographic  locations
        that enable us to leverage  existing power generation assets and operate
        the power plants as integrated electric generation systems.  This allows
        us to achieve  significant  operating synergies and efficiencies in fuel
        procurement, power marketing and operations and maintenance.

    o   Acquisition of power plants. Our strategy is to acquire power generating
        facilities  that meet our  stringent  acquisition  criteria  and provide
        significant  potential for revenue,  cash flow and earnings growth,  and
        that provide the  opportunity to enhance the operating  efficiencies  of
        the plants. We have  significantly  expanded and diversified our project
        portfolio through the acquisition of power generation facilities.

    o   Enhance the performance  and efficiency of existing power  projects.  We
        continually  seek to  maximize  the power  generation  potential  of our
        operating assets and minimize our operating and maintenance expenses and
        fuel costs.  This will become even more  significant as our portfolio of
        power generation  facilities  expands to an aggregate of 72 power plants
        with  a net  capacity  of  17,265  megawatts,  after  completion  of our
        projects  currently  under  construction  and  development.  We focus on
        operating our plants as an integrated system of power generation,  which
        enables us to minimize  costs and maximize  operating  efficiencies.  We
        believe that achieving and  maintaining a low-cost of production will be
        increasingly  important to compete  effectively in the power  generation
        market.
